Using this pet carrier is a breeze. First, put the harness on your pet. Then, gently place your pet inside the carrier. You can adjust the straps to fit your shoulder comfortably for easy carrying. When traveling, make sure your pet has enough air circulation. Check the carrier regularly to ensure your pet is safe and comfortable. If your pet is larger, unzip the bottom zipper to expand the base. For maintenance, clean the carrier regularly with a mild detergent and let it air - dry. Avoid using harsh chemicals as they may harm your pet. Store the carrier in a cool, dry place when not in use.
